1 Claim. (Cl. 1697) This invention relates to hinges and track engaging roller supports for slidably mounted doors of the upwardly acting sectional type having track-s rearwardly inclined relative to the door frame or jamb.

The main objects of this invention are:

First, to provide a combined hinge and roller support for sectional doors of the type including tracks having upright sections rearwardly or inwardly inclined relative to the door jamb.

Second, to provide a combined hinge and roller support which provides means for very quick and accurate adjustment of the roller support relative to the door and at the same time is capable of withstanding severe shocks and stresses Without displacement or dislocation of the roller carried thereby.

Third, to provide an adjustable roller support having these advantages which may be used in association with a hinge or as a bracket where conditions require only spindle support.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claim.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

FIG. 1 is a fragmentary vertical section of a door embodying our invention, certain parts being shown conventionally.

FIG. 2 is an enlarged fragmentary view in vertical section on a line corresponding to line 22 of FIG. 3.

FIG. 3 is a fragmentary view partially in section on a line coresponding to line 3-3 of FIG. 2.

FIG. 4 is a fragmentary view mainly in section on a line corresponding to line 44 of FIG. 2.

FIG. 5 is a front view of a combined hinge and roller spindle supporting bracket embodying our invention.

FIG. 6 is a front view of the hinge unit.

FIG. 7 is a front view of the bracket unit.

FIG. 8 is an end elevational view of the bracket unit.

FIG. 9 is a fragmentary front end view of the bracket and spindle support, the bolt being omitted.

FIG. 10 is a front view of the spindle support member.

FIG. 11 is a side view of the spindle support.

FIG. 12 is a perspective view of the spindle support securing bolt.

In the accompanying drawing 1 represents a door frame, 2 the seal thereof and 3 a jamb. In practice the jamb is desirably resilient but as the particular jamb forms no part of this invention it is conventionally illustrated.

The door is of the upwardly acting sectional type comprising an upper section 4, a bottom section 5 and intermediate section 6. The track includes the upright rearwardly inclined sections 7, horizontal sections 8 and a curved intermediate section 9 merging into the upright and horizontal sections. It will be understood that there are two of these tracks in an assembly. This arrangement of tracks is old in the art and therefore is not further described but the invention of this application is particularly desirable for installations, such as illustrated in which the track engaging rollers 10 are supported relative to the plane of the door so that when the door is in closed position it is sealingly forced against the jamb.

An object of this invention is to provide a combined hinge and support for the roller spindle 11 and one which may be quickly adjusted where installed to compensate for the particular inclination of the tracks and for structural variations or conditions of a particular installation, variations in jamb seals and the like: also, to provide roller supporting bracket assemblies which may be assemled with the hinges of the particular assembly or used independently thereof to support the rollers, for example, adjacent the bottom door section and the upper edges of the upper section. Such adaptations are illustrated in FIG. 1.

The combined hinge and roller support of the embodiment of this invention illustrated comprises the leaf hinge members 12 and 13 provided with knuckles 14 and 15 respectively connected by pintle 16. The hinge members are provided with longitudinally extending parallel ribs 17 and 18, the hinge member 15 also having lugs 19 struck outwardly therefrom adjacent the knuckles.

The spindle supporting bracket comprises a base member 20 and outwardly projecting bracket arm 21 integral therewith and disposed angularly relative thereto. The base member is provided with longitudinally extending ribs 22 which extend into the bracket arm at 23, see FIG. 8. The ribs 22 are spaced to provide inwardly facing grooves which embrace the ribs 18 of the hinge member 13.

The base member of the bracket is provided with side flanges 24 which merge into the side flanges 25 of the bracket arm. The bracket member is secured to the hinge member on which it is superimposed and to the door section where it is used in connection with the hinge by the bolts 26. Where used independently of the hinge as on the top and bottom sections it is secured directly to the door by bolts 27, see FIG. 1.

The bracket arm is provided with a longitudinal slot 28 having opposed notched side edges, the edges of the slot are also provided with notches 29 in its end edges. The spindle support 30 is provided with flanges 31 on its side edges which embrace the flanges on the outwardly projecting arm of the bracket.

The spindle support is provided with a socket 32 for the spindle 11 and has a slot like bolt opening therein, the side and end edges of which are notched at 34. This socket member, desirably formed of sheet metal, is in the embodiment illustrated provided with reinforcing ribs 35 which extend from each side of the opening 34 onto the flanges 31.

The spindle support may be reversibly positioned upon the bracket as is illustrated in FIG. 1, thus providing a wide range of adjustment in proportion to the length of the outwardly projecting arm of the bracket. It is secured in its adjusted position by means of a bolt 36 having a noncircular shank portion 37 preferably rectangular and provided with lugs 38 on each side thereof engageable with the notches in the opposed side edges of the slot in the bracket arm member and with the notches in the slot in the spindle support member.

While the bolt is provided with a nut 39 and a washer 40 is desirably used the load shocks to which the spindle support may be subjected is sustained by the engagement of the lugs with the notches. These notches are desirably closely positioned as illustrated which permits very accurate adjustment of the spindle support to meet particular types of installations. The spindle support may be reversibly positioned upon the bracket which is illustrated and adds further to the range of adjustment. This adjustment is made on the job and can be made by a relatively unskilled workman, at the same time the parts are efiectively secured in their assembled relation.

Another advantage is that the hinge members and spindle support parts may all be, and desirably are, formed .3 as sheet metal stampings. The bolt shank 37 is especially designed for the particular assembly forming the shank of rectangular section and providing a lug on each side thereof and serves to prevent the assembling of the structure without lugs being in engagement with the notches and when the bolt is disposed at the extreme ends of the slot of the bracket spindle support one of the lugs engage the notches in the adjacent end of the slot.

We have described and illustrated our invention in a highly practical commercial 'form. We have not attempted to describe other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired.

Having thus described the invention what is claimed as new and desired to secure by Letters Patent is:

A combined hinge and roller spindle support for upwardly acting doors of the type including horizontally disposed sections and tracks including upright sections inclined relative to the door frame, a track engaging roller provided with a spindle, a hinge comprising a pair of leaf hinge members provided with aligned knuckles and a coacting pintle, one of said hinge members having outwardly projecting longitudinally extending laterally spaced parallel ribs and being provided with outwardly projecting lugs adjacent its knuckles, a spindle bracket comprising integral angularly disposed base and arm members having merging flanges on their edges, the base member being disposed and clampingly secured upon the hinge member having said lugs with its inner end in end thrust 30 supported engagement with said lugs and having outwardly offset longitudinally extending inwardly facing grooves dimensioned to supportedly embrace said ribs on said hinge member, said ribs on said bracket being extended into said bracket arm member, said bracket arm member having a centrally disposed longitudinally extending slot therein having opposed notched side edges, a spindle socket member having a spindle socket at one end thereof and having flanges on its side edges embracing the flanged edges of said bracket arm member, said socket member having a bolt opening therein having notched side edges and also having transverse ribs on each side of the bolt opening extending into its flanges, and a bolt provided with a nut and having a shank cross sectionally dimensioned to supportedly fit between the opposed edges of said bolt opening in said socket member and said slot in said bracket arm, said shank having lugs on opposed sides thereof selectively engageable with said notches in the edges of said arm member slot, whereby said spindle support may be variably positioned on and secured to said bracket arm member.
